Werewolves in the Weidner? Creepy creatures in the Cofrin Family Hall? You just might see both during a special Halloween concert featuring UW-Green Bay’s Concert Choir and Symphonic Band. UW-Green Bay students and children from the community will get in free when they come in costume, and we have a hunch adults dressed up will be welcomed as well. The show will be semi-Halloween themed, with regular pieces and spooky selections alike. Tickets are $7 for adults and $5 for students and seniors, with the aforementioned free-ticket costume caveat. Should be a semi-spooky good time. Full details.
